Specification of Letters Patent.

Patented Jan. 7, 1919.

Original application filed December 20, 1917, Serial N o. 208,047.Divided and this application filed April 29,

` f 1918. Serial No. 231,477.. 'I

To all/whom t may concern.'

Be-Iit known that I, y(1H/ARLES M. DRINK- WATER, a citizen of the UnitedStates, residing at Kokomo, in the county of Howard and State ofIndiana, have invented certain new and luseful Improvements in `AshSifting Apparatus, of which the following is a speciiication.` `l j;

My presentlinvention pertains to ash sifting' and `analogous apparatus,and is designed more particularly, though not necessarily,

for embodiment in the apparatus constituting the subject of mycontemporary application Ifiled December- 20, 1917, 'SerialNumber268,047of which' thisapplication is a divi- Slon.. p v. j

One of the objects ofthe present'invention is theY provision ofy anash-sifting or analogous apparatus in whichfthej throat usually employedto support a dust-confining valve isY joined'tolthebodyon which it ismounted in such manner that the escape of dust between the two isabsolutely precluded.

Another object of the invention is the provision of an ash-sifterbodysusceptible of beingexpeditiouslyand easily knocked down. or taken apartso as to occupy but small coin'-y y pass in storage or shipment, and oneadapted to be as readily set up with its parts joined in such mannerthat it is ready for efficient use, and this without the employment ofskilled labor.

Other objects and advantageous features of the present invention will befully understood from the following description and claim when the sameare read in connection with the drawings, accompanying and forming partof this specification, in which:

Figure 1 is a longitudinal vertical section of so much of an ash-siftingapparatus as is necessary to illustrate the preferred -application of myinvention.

Fig. 2 is a vertical transverse section taken in the plane indicated bythe line 2-2 of Fig. 1.

Fig. 3 is a top plan view of a portion of the apparatus.

Similar numerals of reference designate corresponding parts in all theviews of the drawings.

My present invention is preferably, though not necessarily, embodied inan ash-sifting apparatus, and in addition to a throat 1 for supporting aflaring mouth 2 and a dust-conning valve 4 or the like, the apparatuscomprises a body 12 on which the throat is su-` perimposed. In' thepresent and preferred embodiment of the invention there is aninclinedsifting screen 13 in the body, a vertically-slidable door 14disposed in guides at theforward end of the ybody for the convenientremoval of cinders from the forward portion of the body bottom, a baieplate 15 disposed at approximate right angles to the screen 13 and inspaced relation to the lower end thereof, a compartment 16 below thescreen and isolated from a. cinder compartment 17 by a transverse wall18, and a drawer 19 designed to receive ashes and having handles 20`and21 at its opposite ends; said drawer l.being removable through anopening in .the forward wall of body 12 and being anged, as indicatedb-y22, to effectually close said opening when th position to receiveashes.. i

The lower end of the throat lisl provided with loop-flanges 23 thatstraddle the upstanding wall portions about the induction e drawer is inorice of the body 12. Thus the throat is l supportedon the body in such'manner that theV oint between the two is broken and the escapeof dustprecluded, and yet the throat may when necessity arises be readilylifted oli the body and as readily replaced thereon.

Thev side walls 24 of the body 12 are provided on their upper edges withinwardlydirected flanges 25, Figs. 3 and 4, and the -top wall 26 isinterlocked with said flanges 25, as indicated by 27 to break jointsbetween the parts, strongly connect the same, and lend rigidity andstrength to the body as a whole, as well as to permit of the wall 26being drawn out of engagement with the walls 24 when it is desired toship or store the body in a knock-down state. At its lower end the wall26 is interlocked with the upper end of the baiiie plate 15, asindicated by 28, Fig. 1, and at its upper end said wall 26 isinterlocked with an upstanding wallv dust-proof broken joint manner, andyet of interlockedjoints 33 for 'dust-proof and,v strength-lend,inglpurposes. .as well as :to per.; mit of the frontwall beingreadilydra'wn,

out of engagement with the side walls for knock-,down purposes,.whi lethescreen 13 is bolted to thesidewalls 24, as indicated by', 34, thebaffleplatel and wall 18 arealso'.;` bolted to said kside walls, as.indicated ,by-g 35 and 36, respectively, thelwall :18,is bol`ted',.v tothel screen 13,` as indicated by 37, andthe:`v said screenkis bolted .tothe frontwall 32. as indicated by. 38. Manifestlytwhenithel, said boltsare removed, the .bodywallsfmay ,y be disassembled :in themannerv beforeindi-v cated for vthe i purposes. described, and Y when the said `wallsare relatively vvarranged and`r engaged in the setting vup, of thebodyand.` the bolts 4arevplaced and secured in position..

a rigid and strongbodykwill be produced..
